1. A package comprising(a) a first absorbent article;
- (b) a wrapping material wrapping at least a portion of said first absorbent article, the wrapping material having at least a first region and a second region being comprised of the same material composition, said first region undergoing a substantially molecular-level deformation and said second region initially undergoing a substantially geometric deformation when said wrapping material is subjected to an applied elongation along at least one axis.

Abstract
A package including a web material that exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having at least two visually distinct regions of the same material composition. The first region undergoes a molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the web material is subjected to an applied elongation in a direction substantially parallel to the axis of elongation.

9. A package for one or more individually wrapped absorbent articles comprising:
-
(a) a first absorbent article; (b) a first wrapping material wrapping said first absorbent article, the first wrapping material having at least a first region and a second region being comprised of the same material composition, said first region undergoing a substantially molecular-level deformation and said second region initially undergoing a substantially geometric deformation when said wrapping material is subjected to an applied elongation along at least one axis; and (c) a second wrapping material wrapping at least a portion of said individually wrapped first absorbent article, the second wrapping material having at least a first region and a second region being comprised of the same material composition, said first region undergoing a substantially molecular-level deformation and said second region initially undergoing a substantially geometric deformation when said wrapping material is subjected to an applied elongation along at least one axis. - View Dependent Claims (10, 11, 12, 13)
